the following reaction gives a product with the molecular formula c4h8o2. draw the structure of the product.
grandymaker [24]

The following reaction gives a product with the molecular formula C₄H₈O₂. The diagram of the structure of the product can be seen in the image attached below.

The reaction between C₂H₂(ONa)₂ and C₂H₄Br results in the formation of the product C₄H₈O₂ and 2NaBr.

This reaction undergoes an SN₂ mechanism since there is no stable carbocation formed. In the reaction -O⁻Na⁺ attacks the ortho position in C₂H₄Br to form C₄H₈O₂.

In  SN₂ mechanism is a nucleophilic substitution reaction where one bond is formed while another one is broken simultaneously.

The mechanism for the reaction can be seen in the image attached below.
